VALVE FOR PUMPS.

Specification of Letters Patent No. 9,046, dated June 22, 1852.

YTo all whom it may concern.'

Be it known that I, JOEL R. BAssE'rT, of Cincinnati, Hamilton county,Ohio, have invented a new and useful Improvement in Double-Acting Pumps;and I do hereby de- Clare the following to be a full, clear, and exactdescription of the same, reference being had to the annexed drawings,made part of this specification.

The device I use consists of a cylindrical box-valve (the top and bottomof which are slightly conical) and a valve-chest adapted thereto, eachhaving the parts necessary to the operation of a double acting lift andforce pump, thus obtaining from a single valve deriving its motion fromthe outflowing and inflowing currents the result for which severalseparate valves have hitherto been needed.

In the annexed drawings Figure 1 is a perspective view of the pump, thevalve and chest-cap being detached; Fig. 2B, is a horlzontal sectionthro-ugh the water-bed, valve and valve-chest looking downward, and Fig.2A is a top view of the chamber-cap with one opening closed by the valveand the other opening unclosed.

The same letters refer to like parts throughout.

(a) is a double-acting pump cylinder of usual construction; is the usualsidepipe.

The water bed seen exteriorly at (0), Fig. 1, consists of the twopassages (0') (0), Fig. 2B, one of which (0') communicates with thebottom of the cylinder (a) and the other (0) through the side pipe (o)with the top of the cylinder (a). Each of these passages opens into thechest (CZ), as seen in the instance of the passa-ge (0) at (e), Fig. l.This chest is circular and with a view to wear and adjustment slightlyconical, tapering downward, and has fitted nicely to its interior acorrespondingly formed box-valve (f) having openings (g) (g) in it-sside corresponding to those in the chest. These openings (g) (g) havecommunication with the suction pipe below by means of apertures (t) (z)in the bottom of the valve, and these apertures, through correspondingopenings (one of which is seen at (L) in Fig. 1) in the chest-bottom(Z), and with the escape-pipe above by means of apertures (i) (2)through corresponding openings (im) in the cap (m), so that as regardsthe valve, when the lower aperture (t) on one side is in communicationwith the aperture (M) in the flow, the lower aperture on the other sideof the center of the valve is closed and at the same time the upperaperture of the valve is shut off from (im) in the cap and the aperture(z') corresponds with the aperture (zw) and vice-versa on the reversestroke.

l/Vhen the pump is operated the currents forced therefrom or admittedthereto strike opposing vertical sides of the box-valve openings and actin concert to give the valve a vibratory motion limited by the pinworking in the groove (7n) the motion being a little more than doublethe width of the openings or (7L), but inasmuch as the current due tothe forcing stroke of the pump somewhat more than counterbalances thecurrent due to the column raised by atmospheric pressure, 0r in commonparlance, to the lifting stroke of the pump, it is the current forcedout of the pump that determines the motion of the valve. In the drawingsthe current due to atmospheric pressure is supposed to be rising upthrough the opening (/L) overlying the opening (z/) and passing throughthe openings (g) and (e) into the waterway (0), and the current due tothe forcing stroke is passing out from the waterway (0) through theopenings (g) and (vY) into the usual air-vessel from which the dischargeof the water vis made in the usual way.

What I claim as new and desire to secure by Letters Patent of the UnitedStates is- The device consisting of a cylindrical box-Valve with itsinduction openings (77,) L) and its side or waterway openings (g) g) andits eduction openings (2), and of a valve-chest adapted thereto with itsinduction and side, or water-way, and eduction openings corresponding tothe openings in the valve-box; the whole, in connection with the usualwaterways and barrel of a double-acting pump, furnishing the partsnecessary to the operation of such a pump; thus obtaining from a singlevalve, deriving its motion from the outilowing and inflowing currents,the result for which several separate valves have hitherto been needed,substantially in the manner described.
